This is a high fee transaction yet still unconfirmed. I've checked mempool and there's a lot of unconfirmed transactions.
Try your luck pushing that transaction through:
https://www.viabtc.com/tools/txacceleratorOr use the bitaccelerate -
https://bitaccelerate.com/. Whenever I make btc transaction, I use this free accelerator afterwards. OP's transaction will be soon confirmed. But 19 hrs and still waiting, paying 176 sat/byte, usually that payment amount before will only take few minutes.
bitaccelerate only rebroadcast transaction but
https://www.viabtc.com/tools/txaccelerator is the only working accelerator. It seems to be beyond the limit due to requests.
I don't find bitaccelerate to be effective, I've used it a lot of times before when there's such congestion before but to no avail.
Btw, @OP, congratulations your transaction got 24 confirmations already. I think the thread is already good enough to be closed.
I'm not surprised the transaction was confirmed while you make your post but Bitaccelerate is not for transaction acceleration cause it was used to re-broadcast transactions which seems to be forgotten in the mempool.
Transaction confirmation delay doesn't mean Bitcoin did not serve it purpose anymore if you follow the right procedure before sending your transaction and paying a huge transaction doesn't matter either if you don't check the mempool condition.
And you can check the mempool conditions four hundred million times, can you people just stop with this non-sense?
You can look at that mempool all day long, it won't change the fact that if you want to send now even the smallest transactions (in size) you have to pay 8$.
Everyone is saying look at your inputs, look at the mepool size look at whatever!
I understand that's the condition of the Bitcoin network right now in spite that, like it or not people still need to check the mempool condition using the Bitcoin transaction fee estimator to avoid long/stuck transactions.
